arch/x86/kvm/svm/sev.c: change flag passed to GUP fast in sev_pin_memory()
...
When trying to lock read-only pages, sev_pin_memory() fails because
FOLL_WRITE is used as the flag for get_user_pages_fast().

KVM: SVM: Fix build error due to missing release_pages() include
...
Fix:
arch/x86/kvm/svm/sev.c: In function ‘sev_pin_memory’:
arch/x86/kvm/svm/sev.c:360:3: error: implicit declaration of function ‘release_pages’;\
did you mean ‘reclaim_pages’? [-Werror=implicit-function-declaration]
360 | release_pages(pages, npinned);
| ^~~~~~~~~~~~~
| reclaim_pages
because svm.c includes pagemap.h but the carved out sev.c needs it too.
Triggered by a randconfig build.

KVM: SVM: fix compilation with modular PSP and non-modular KVM
...
Use svm_sev_enabled() in order to cull all calls to PSP code. Otherwise,
compilation fails with undefined symbols if the PSP device driver is compiled
as a module and KVM is not.
